Qld 100k mapsheets - Warwick

Abstract

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied. The polygons in this dataset are a digital representation of the distribution or extent of geological units within the area. Polygons have a range of attributes including unit name, age, lithological description and an abbreviated symbol for use in labelling the polygons. These have been extracted from the Rock Units Table held in the Department of Natural Resources, Mines and Energy Merlin Database.

Purpose

To display the geology polygons which define the extent of rock units.

Dataset History

Supplemental_Information:

Data captured at 1:40 000 scale. The data set is sourced from the Department's Geoscience and Resources Database (GRDB), a component of the Mineral and Energy Resources Location and Information Network (MERLIN) corporate database.(GRDB), a component of the Mineral and Energy Resources Location and Information Network (MERLIN) corporate database.



NOTE: GEOLDATA was in most cases compiled based on Datum AGD66. The map tile coverages so compiled have now been projected to geographics based on Datum GDA94. Consequently the boundaries for these map tiles will not conform to the Latitude and Longitude graticule based on Datum GDA94.

Detailed_Description:



    Entity_Type:



        Entity_Type_Label: 9341_r

        Entity_Type_Definition:

            Polygons have a range of attributes including unit name, age, lithological description and an abbreviated symbol for use in labelling the polygons.

        Entity_Type_Definition_Source:

            The Rock Units Table held in the Department of Natural Resources, Mines and Energy Merlin Database.



    Attribute:



        Attribute_Label: FID

        Attribute_Definition: Internal feature number.

        Attribute_Definition_Source: ESRI

        Attribute_Domain_Values:



            Unrepresentable_Domain:

                Sequential unique whole numbers that are automatically generated.



        Beginning_Date_of_Attribute_Values: March 2004



    Attribute:



        Attribute_Label: Shape

        Attribute_Definition: Feature geometry.

        Attribute_Definition_Source: ESRI

        Attribute_Domain_Values:



            Unrepresentable_Domain: Coordinates defining the features.



    Attribute:



        Attribute_Label: KEY

        Attribute_Definition: Unique polygon identifier and relate item for poygon attributes



    Attribute:



        Attribute_Label: ROCK_U_NAM

        Attribute_Definition:

            The Map Unit Name of the polygon. In the case of named units it comprises of the standard binomial name. Unnamed subdivisions of named units include the binomial name with a letter symbol as a suffix. Unnamed units are represented by a letter symbol, usually in combination with a map sheet number.



    Attribute:



        Attribute_Label: AGE

        Attribute_Definition: Geological age of unit



    Attribute:



        Attribute_Label: LITH_SUMMA

        Attribute_Definition:

            Provides a brief description of the map units as they have been described in the course of the project work, or as has appeared on relevant hard copy map legends.



    Attribute:



        Attribute_Label: ROCK_U_TYP

        Attribute_Definition:

            Provides a means of separating map units, eg for constructing a map reference. This item will contain one of the following: STRAT- Stratigraphic unit, including sedimentary, volcanic and metamorphic rock units. INTRU- Intrusive rock units; COMPST- Compound unit where the polygon includes two or more rock units, either stratigraphic, intrusive or both; COMPST- Compound unit, as above where the dominant or topmost unit is of the STRAT type; COMPIN- Compound unit, as above, where the dominant unit is of the INTRU type; WATER- Water bodies- Large dams, lakes, waterholes.



    Attribute:



        Attribute_Label: SEQUENCE_N

        Attribute_Definition:

            A numeric field to allow sorting of the rock units in approximate stratigraphic order as they would appear on a map legend.



    Attribute:



        Attribute_Label: DOMINANT_R

        Attribute_Definition:

            A simplified lithological description to allow generation of thematic maps based on broad rock types.



    Attribute:



        Attribute_Label: MAP_SYMBOL

        Attribute_Definition:

            Provides an abbreviated label for polygons. Mostly based on the letter symbols as they appear on published maps or the original hard copy compilation sheets. These are not unique across the State, but should be unique within a single map tile, and usually adjacent tiles.



    Attribute:



        Attribute_Label: NAME_100K

        Attribute_Definition: Name of 1:100 000 map sheet coincident with the data extent.



Overview_Description:



    Entity_and_Attribute_Overview:

        Polygon Attribute information includes Polygon Key, Rock Unit Name, Age, Lithology, Rock Unit Type, Map Symbol and 1:100 000 sheet name.
